A small portable C++11/14/17/20 template project with Makefile/CMake project files to use on any platform as a starting point

This is a C++ example project I use to test features and code within a small testable environment. It includes a cmake build project and a Makefile build project. I am currently forcing myself to use and learn the cmake environment so its more second nature to me again.

It should be noted that if you are using clang and boost on a Linux platform then be very wary. The boost that is installed via apt-get is most likey (no always) compiled via G++ using the libstdc++. This means when it has a source file which defines a function that either takes/returns a std::string then it will be compiled using the libstdc++ definition of the std::string (those bits). But when you compile the main.cpp and include the same boost header file it will see the definition of the function with the std::string defined as the bits being as defined by libc++. CORE DUMP!

Since cmake should not be placing the build artifacts within the source tree create a sibling directory outside the source tree and execute the commands to build:

If using the following testcpp directory:

~/code/test/testcpp mkdir ~/code/test/build cd ~/code/test/build CC=clang CXX=clang++ cmake ../testcpp make
